Guangxi Nanning power supply department actively deploys anti icing work to ensure the safe operation of power grid
2021-12-29
Affected by the strong cold air, there are rime and rime in some areas of Daming Mountain in Nanning. The icing thickness of 10kV two micro lines of Guangxi Nanning Wuming Power Supply Bureau of China Southern Power Grid is 7.68 ~ 8.66mm. In order to ensure the safe and stable operation of the power grid, Nanning Wuming Power Supply Bureau went up the mountain for monitoring at the first time to respond to the anti ice work.
In winter, under the condition of continuous wet, cold and freezing rain, the natural disaster of freezing occurs in Daming Mountain at high altitude, which makes the power supply line of Daming Mountain prone to icing and has a great impact on the power supply safety. "In order to ensure the orderly development of anti icing and anti icing work this year, we arranged in advance, made every effort to ensure the safe and stable operation of the power grid, and put an end to power outages caused by line icing." LAN Yi, deputy general manager of Nanning Wuming Power Supply Bureau.
Nanning Wuming Power Supply Bureau deployed from the aspects of technical force team preparation and information submission. According to the arrangement of the anti ice and anti ice emergency drill plan, the Luu power supply station of the Bureau completed the power on inspection of the function of the ice melting device on September 10, transported the ice melting device to Daming Mountain and put it in place on November 26, completed the transformation of the base of the ice melting device, and completed the preparation of primary and secondary wiring.
On December 1, the Bureau carried out an emergency ice melting simulation drill on the line against low temperature and strong freezing disasters in Daming Mountain to test the DC ice melting effect and the emergency response ability against rain, snow and freezing disasters. Since the 23rd, the icing value of 10kV two micro wires and the stability of conductor tension have been monitored through the system every day and reported in time.
At the same time, in combination with operation experience and meteorological prediction, the office also conducted special patrol on the key pole numbers, important icing observation points, important crossing, large span, mountain crossing tuyere and landslide prone sections of the equipment and lines under its jurisdiction. At the same time, strengthen the establishment of communication mechanism with local governments and meteorological departments to jointly maintain the normal power supply order.
Up to now, the Bureau's three emergency repair teams are in full readiness for anti icing and anti icing work, so as to ensure that the emergency repair team can actively respond to dangerous situations at the first time and ensure the safe, stable and reliable operation of Daming Mountain line.
